Thebarometer works bybalancing the weight of mercury in the glass tube against the atmospheric pressure, much like a set of scales. Atmospheric pressure is basically the weight of air in the atmosphere above the
The air pressure for a tire is 109 kPa. What is this pressure in atmosphere? The pressure of the earth's atmosphere at sea level is 14.7 lb/in^2. What is the pressure when expressed in kg/m^2? The surface of a planet has ...
Because atmospheric pressure is relatively constant, the pressure in the lungs must change to create airflow between the lungs and the outside environment. During inhalation (inspiration), the diaphragm and supporting muscles (intercostal muscles) contract, which results in an expansion of the thoracic...
The conversion factor between atmosphere and torr is required to convert a value in the atmosphere unit to torr. It may be noted that one atmospheric pressure is equal to 760 torrs.Answer and Explanation: The conversion factor (f) between atm and torr is shown below: f=760torr1atm ...
The vertical axis represents the pressure that it takes to obliterate the rock, measured in MPa, or millions of Pascals (to go from MPa to atmospheric pressure, just multiply by 10). The horizontal axis has to do with how porous the rock is. The figure includes data using rock ...
collapsedaround 3.7 billion years ago, and it lost its atmosphere. Now, Mars has a very thin atmosphere: the atmospheric pressure on theMartian surfaceaverages 600 pascals (0.087 psi; 6.0 mbar), about only 0.6% of Earth’s mean sea level pressure of 101.3 kilopascals (14.69 psi; 1.013 bar...
(mmHg) is a unit of pressure typically used in measuring blood pressure. The kilopascal (kPa), which is 1,000 pascals, is a metric pressure unit used to gauge a variety of pressures, from atmospheric to internal pressure. Millimeters of mercury can be converted to kilopascals using simple ...
3. Normal atmospheric pressure at sea level is generally considered to be equal to the pressure exerted by a column of mercury 760mm high. Calculate the corresponding pressure in inches of mercury and in Pascals. 4. The hydraulic lift in a service station is capable of raising cars with a...
In a vacuum environment, the absolute pressure of the gas is much lower than the typical atmospheric pressure at sea level, which is about 101,325 pascals (Pa) or 14.7 pounds per square inch (psi). The atmosphere is mostly nitrogen and oxygen, but when dealing with vacuum chambers, we mu...
pressure-patterns are as important as they are down here at the surface. Atmospheric pressure is simply an expression of the force applied by a column of air upon a fixed point of known area, and is measured in pascals (Pa). Meteorologists use the hectopascal (hPa) because the numbers are...
